Operation 
 

Plug the NT25-P18 into the wall outlet. To test the safety switch unplug the pump, and pour water 
into the NT25-P18 tank until the safety switch contacts open. Plug the pump in and the pump 
should turn on. Ensure there are no leaks or kinks in the piping.  
 
During operation the appliance condensate will flow through the neutralizing media, raising the 
pH of the condensate to a level that will help prevent corrosion of the domestic drain and the 
public sewer system. The pump will then remove the condensate to desired location (i.e. drain). 
See figure 5 above.
